The detection of drugs or other toxic substances can be crucial to forensic investigations. However, if the investigation involves a heavily decomposed, skeletonized, or missing corpse, that information can be difficult to obtain, and may require the skills of a unique branch of forensic toxicology-entomotoxicology. To explain the role of chromatography in this field, The Column spoke to Paola A. Magni from Murdoch University, in Perth, Australia.

Highly repeatable fragmentation of the compounds into the ion source is one of the major advantages of using gas chromatography coupled with electron ionization mass spectrometry (GC–EI-MS) for the analysis of volatile and semivolatile compounds. The generation of intense and diagnostic fragmentation when the ionization is performed at 70 eV has been used for the creation of many established databases-enabling the analyte identification process.

The addition of a light scattering detector dramatically increases the capabilities of gel permeation chromatography/size-exclusion chromatography (GPC/SEC) analysis. However, the complexity of the system also increases. This instalment of Tips & Tricks discusses column issues when working with light scattering detectors.

A fully automated method for the effective drug screening of large populations based on dried blood spot (DBS) technology is presented. DBSs were prepared, scanned, then spiked with deuterated standards, and directly extracted, before they were transferred online to an analytical liquid chromatography (LC) column and then to the electrospray ionization tandem mass spectrometry (ESI-MS/MS) system. The method was applied to DBS samples from two patients with back pain; codeine and oxycodone could be identified and quantified accurately below the level of misuse of 89.6 ng/mL and 39.6 ng/mL, respectively.
